Gasketing tape insures the best possible results from your air filters. By applying this temperature rated tape around the perimeter of your air filters, a tighter seal is established, thus preventing "blow-by" (leakage) of air passing around a filter. Ads up to 1" of diameter to filter. Also used for quieting rattles from blower doors.

Single sided black 1/2" thick PVC foam tape. Low density closed cell PVC foam coated on one side with a high performance acrylic adhesive. Has very good flexibility and conformability with high strength, chemical, wear and moisture resistance. Used in automotive, HVAC, construction industries and for gasketing in speaker and electronic components. Also used for filling and sealing gaps around windows, doors, and car/SUV tops for better insulation.

No more excuses of even the best filters won't work 100% of the time because of the gaps all around them. This gasket tape will make your air filter super tight fit so that it will catch more OMG stuff in the air. Your lungs won't have to work as a part of the air filter any longer. I breathe easy now.

There was a large gap between the entry doors of my home. The weather stripping needed to fit into a grove in the stationary door and no product of this type was available for use as a weather seal replacement. I originally purchased the material to use around my A/C filters to make them fit more snugly in the air return. There was enough material to do that job and to apply to the door. It is working wonderfuly, I have probably saved more than the cost of the product just in the last three weeks.

Works well for filters 1/2 inch smaller than the vent opening if you place a strip of the gasket tape on two sides of the vent opening. If you place a strip of the tape on all four sides of the opening the filter won't fit.

Most filters are too small for the filter back grilles in your return air opening. Even if you have a perfectly sized match of grille and filter, the filter lets a lot of air get sucked around its corners and edges unfiltered (and often noisy). Using a Filter gasket is well worth the few extra dollars. Makes a tight seal around filter, increases efficiency and quietness of filters. Get some!
